LATCH.

Application filed March 5, 1925.

This invention relat-es to improvements in latches for doors and otherhinged members, an object being to provide a latch which will securelyhold a doorin closed position and which will be released simultaneouslywith either the pushing or pulling. action when opening the door.

Another obj ect of the invention is the prof vision of a latch as abovestated which is simple in construction, ethcientk in use and which maybe adapted for use upon screen doors, public halls, theaters and soforth.

Vith the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

In the drawings Figure 1 is a fragmentary sectional view illustratingthe latch in use.

Figure 2 is an enlarged fragmentary section of the same partly-brokenaway.

Figure 3 is a detail perspective view of p the keeper.

Figure 4y is a sectional view showing a modified form of the invention.

Referring in detail to the drawings wherein like characters of referencedenote corresponding parts, the reference character 10 indicates aportion of a door, for example a screen door, the frame of the doorbeing provided with a stop 11 against which the free edge of the doorengages to limit swinging movement in one direction.

Secured to the door by screw-s 12 or simi-V lar fastening devices is abracket 13. This bracket is provided vwith an offset portion orextension 14 which forms a latching shoulder which is adapted to engagea keeper plate 15. One end of the plate 15 is secured to the door frameby lscrews or other fastening devices 16 and `the opposite end of theplate is relatively offset and is spaced from the frame. The plate isprovided with an opening so as to form a shoulder' 17 at one edge of theopening, the latching shoulder 14 of the bracket 13 engaging thisshoulder 17 and when so engaged will prevent outward swinging movementof the door.

Pivo-tally secured at one end of the bracket 13 as indicated at 18 is alatch bar 19. In Figures 1 and 2, this bar is substantially L-shaped andis positioned so that oneof its arms 2O will engage the free end of theSerial No. 13,358.

keeper plate and move the latter out of the path of the latchingshoulder 14. To accomplish this the outer end of the latch bar 19 hasextending therethrough the shankv of a knob 21, the inner end of thisshank being secured to the Ishank 22 of a knob 23. The knob 23 islocated upon the outside of the door and the shank 22 extends lthroughthe door and through a plate 24 secured uponv said door.

A pull upon the knob 23 for the purpose of pulling the door 10outward,-will inove the latch bar 19 pivotally and cause the arm 2O ofthe said bar to engage the free end of the keeper plate 15 so as to movetheshoulder 17 of said pla-te out of the path of the latching shoulder14 as previously mentioned. A push upon the knob 21` from the inside ofthe door will accomplish the same function so that the act of openingthe door will at the .same time release the latch. When closing the doorthe latching shoulder will engagethe shoulder 17 of the keeper late andthe latter will engage vthe arm 20 of the latch bar 19 so as to properlyposition the vsaid bar.

For the purpose of preventing release of the latch from the outside ofthe door, when desired, there is pivotally secured to the latch bar 19as shown at 25, a locking finger 26. When the free end of this finger ispositioned against the bar as shown yby the dotted lines in lFigure 1,the latch bar will be held against pivotal movement.

In the form of the invention illustrated in Figure 4, the constructionis the same except that the latch bar has its long arm 27 extendedsubstantially across the width of the door and its free end slidinglyengaging the inner face of the door. The free end of the latch bar issupported within a guide 28. By pushing upon the arm 27 of the latch barat any point throughout its length, the said bar will be moved pivotallyto actuate the latch in the manner previously described. In this form ofthe invention the door could not be opened from the outside. The latchshown in Figure 4 is especially adapted for use upon the doors of smalltheaters, halls or other places of public gathering.

The invention is susceptible of various other changes in its form,proportion-s and minor details of construction and the right is hereinreserved to make such changes as properly fall within the scope of theappended claims.

Having described the invention what is claimed iszl. The combinationwith a hinged door, of a bracket carried thereby, an extension providedupon the bracket, a relatively yieldable keeper mounted in the path ofmovement of and engagingthe extension, a pivoted bar carried by thebracket and including an offset end portion arranged ,to engage thekeeper whereby when said bar is moved the bracket will be released, andmeans vcarried by the bar `tor holding the latter against pivotalmovement.

2. rlhe combination with a hinged door, otl a bracket carried thereby,l.an extension provided upon the bracket, a relativelystationaryyieldable keeper mounted `in the path of movement ot the extension,said` keeper comprising` a platehaving anopening therein and a treeopposite end adapted 'to be engaged by the bracket extension, a

pivoted bar carried by the bracket `and including an oli'set end portionarranged vto engage the opposite end ot the lkeeper plate whereby whensaid bar is moved the bracket will be released, and means carried by thebar for holding the latter `against pivotal movement.

3. The combination with a. hinged door, of a bracket carried thereby, anextension upon the bracket, a relatively yieldable keeper mounted in thepath of and engaging the extension, a bar pivotally secured to thebracket, and including an ottset end portion arranged to engage thekeeper whereby the latter may be moved to release the bracket and meanswhereby the bar may be actuated, and means carriedby the bar for`holding the latter against pivotal L.mov-ement.

et. The combination with a hingedydoor, of a Abracket carried thereby,an extension upon the bracket, a relatively yieldable keeper mounted inthe lpath ,of and engaging the extension, a bar pivotally secured to`the bracket, and including an ot'set end portion arranged to engage thekeeper whereby the latter may be moved to release the ,bracket the barwhereby the latter may be moved pivotally, and means carried by the baror holdinotlie latter ac'ainst livotal movement.

5. The combination with a` hinged door, ot a bracket carried thereby, anextension upon the bracket, a relatively yieldable keepernmounted Yinythe path of and engaging-` the extension, a bar pivotally secured tothe bracket, and including an ott'set end portion arranged to engage thekeeper whereby the latter may be moved to release the bracket, meanslocated `upon opposite sides o't the hinged door and operativelyassociated with the bar whereby the llatter may be moved pivotally andmeans whereby the. bar may `be rheld .against lpivotal Vmovement, andmeans carried the bar for holding .the latter against vpivotal movement.

.6. The combinationwith avhinged door, ot a bracket carried thereby, anextension upon the bracket, a relatively yieldable keeper mounted in thepath of and engaging the extension, a bar `pivotally secured to theVbracket, means carried by the bar and engaging the keeper' whereby the.latter may be moved to release the bracket, Vmeans lo-v cated uponopposite sides of the ,hinged door and operatively associated With .thebar whereby the latter 'may sbe moved pivotally and a. locking fingerpivotally secured to the bar and engageable with .the ,door whereby thebar may be held Vagainst pivotal movement.

7. The vcombination with a hinged door,

of a bracket Acarried thereby, an extension upon the bracket, arelatively yieldable keeper mounted lin the path of and engaging theextension, a bar pi-voted on said bracket, and including an offset end.por-A tion arranged to engage the keepery whereby the latter may bemoved to Arelease l.the bracket, and vrmeans slidably Imounted y.on thedoor and opera-ble from either side thereof, andl connected with saidbar tor ,moving the latter pivotally.

In testimony whereof I allix vmy signature.
